Curvature of gastrocnemius muscle fascicles as function of muscle–tendon complex length and contraction in humans

open access: yesPhysiological Reports, 2023
It has been shown that muscle fascicle curvature increases with increasing contraction level and decreasing muscle–tendon complex length. The analyses were done with limited examination windows concerning contraction level, muscle–tendon complex length ...

Linking muscle architecture and function in vivo: conceptual or methodological limitations? [PDF]

open access: yesPeerJ, 2023
Background Despite the clear theoretical link between sarcomere arrangement and force production, the relationship between muscle architecture and function remain ambiguous in vivo.

Rate of force development relationships to muscle architecture and contractile behavior in the human vastus lateralis

open access: yesScientific Reports, 2022
In this study, we tested the hypotheses that (i) rate of force development (RFD) is correlated to muscle architecture and dynamics and that (ii) force–length–velocity properties limit knee extensor RFD.

Ultrasound-derived Biceps Femoris Long Head Fascicle Length: Extrapolation Pitfalls [PDF]

open access: yesMedicine & Science in Sports & Exercise, 2019
ABSTRACT Purpose This study aimed to compare biceps femoris long head (BFlh) fascicle length (Lf) obtained with different ultrasound-based approaches: 1) single ultrasound images and linear Lf extrapolation, 2) single ultrasound images and one of two different trigonometric equations (termed equations A and B), and 3)

Muscle Architecture Adaptations to Static Stretching Training: A Systematic Review with Meta-Analysis

open access: yesSports Medicine - Open, 2023
Background Long-term stretching of human skeletal muscles increases joint range of motion through altered stretch perception and decreased resistance to stretch. There is also some evidence that stretching induces changes in muscle morphology.

Gastrocnemius Medialis Contractile Behavior Is Preserved During 30% Body Weight Supported Gait Training

open access: yesFrontiers in Sports and Active Living, 2021
Rehabilitative body weight supported gait training aims at restoring walking function as a key element in activities of daily living. Studies demonstrated reductions in muscle and joint forces, while kinematic gait patterns appear to be preserved with up
